Quality of Service (QoS):

Support for IEEE 802.1p, IP ToS/DSCP, and ACL-based (MAC/IP source and destination

addresses and VLANs) traffic classification and processing

Traffic shaping and re-marking that is based on defined policies

Eight output Class of Service (COS) queues per port for processing qualified traffic

Weighted Random Early Detection (WRED) with Explicit Congestion Notification (ECN) to help

avoid congestion

Control plane protection (CoPP)

IPv4/IPv6 ACL metering

IP v4 Layer 3 functions:

Host management

IP forwarding

IP filtering with ACLs; up to 256 IPv4 ACLs supported

Virtual Router Redundancy Protocol (VRRP) for router redundancy

Support for up to 128 static routes

Routing protocol support (RIP v1, RIP v2, OSPF v2, and BGP)

Support for DHCP Relay

Support for IGMP snooping and IGMP relay

Support for Protocol Independent Multicast (PIM) in Sparse Mode (PIM-SM) and Dense Mode

(PIM-DM).

IPv6 Layer 3 functions:

IPv6 host management

IPv6 forwarding

Support for static routes

Support for OSPF v3 routing protocol

IPv6 filtering with ACLs, up to 128 IPv6 ACLs supported

Virtualization:

Virtual Fabric vNICs (virtual NICs) with Ethernet, iSCSI, or FCoE traffic on vNICs

Virtual link aggregation groups (vLAGs)

802.1Qbg Edge Virtual Bridging (EVB) is an emerging IEEE standard for allowing networks to

become virtual machine (VM)-aware:

Virtual Ethernet Bridging (VEB) and Virtual Ethernet Port Aggregator (VEPA) are

mechanisms for switching between VMs on the same hypervisor.

Edge Control Protocol (ECP) is a transport protocol that operates between two peers

over an IEEE 802 LAN that provides reliable, in-order delivery of upper layer protocol

data units.

Virtual Station Interface (VSI) Discovery and Configuration Protocol (VDP) allows

centralized configuration of network policies that persist with the VM, independent of

its location.

EVB Type-Length-Value (TLV) is used to discover and configure VEPA, ECP, and VDP.

VMready support:

Up to 2,048 virtual entities (VEs)

Automatic VE discovery

Up to 32 local or distributed VM groups for VEs

NMotion® feature for automatic network configuration migration

Converged Enhanced Ethernet:

Priority-Based Flow Control (PFC) (IEEE 802.1Qbb) extends 802.3x standard flow control to

allow the switch to pause traffic that is based on the 802.1p priority value in each packet's

VLAN tag.

Enhanced Transmission Selection (ETS) (IEEE 802.1Qaz) provides a method for allocating link

bandwidth that is based on the 802.1p priority value in each packet's VLAN tag.

Data Center Bridging Capability Exchange Protocol (DCBX) (IEEE 802.1AB) allows

neighboring network devices to exchange information about their capabilities.
